That's my recollection as well.

On early drives, the point of buffered seek was to allow the electronics
on the drive to use an acceleration profile specifically tailored to
the stepper motor and actuator mass of the drive.  Before buffered
seek, the time to seek n tracks was exactly n times the track-to-track
time.  Buffered seek improved the seek performance considerably for
longer seeks.
